Miasma is an 18+, extreme horror experience based in Chicago, IL.

Extreme haunted house, immersive theater, immersive horror experience, avant-garde performance art: Miasma embraces pieces of all the labels others have applied to us over the years to create unique, narrative-driven extreme horror experiences.

These physically intense, psychologically challenging, emotionally resonate immersive experiences are unlike anything else offered in the country. Fear, sorrow, desperation, revenge, greed, selfishness, hope - Miasma narratives exist beyond the stereotypical genre themes in an effort to tell meaningful horror stories that reach for something deeper in those that experience them.

Operating since 2014, Miasma is one of the longest running extreme horror experiences in the United States.

Due to the extremity of the content within these stories, experiences will remain 18 and older and invite only for the safety of our guests.
